I believe you're getting a WFCO basic three-stage battery charger - bulk, absorption, and float, just no equalize. I've read that it includes temperature compensation, but the sensor is not remote, so I'm not sure how valuable that feature is when the outside temperature is very hot and the inside of the trailer is cool.
Is it better than a single-stage converter - sure. Does it guarantee that your batteries will be cared for as well as they possibly could - no. Is it good enough - probably?
The concern diminishes if you're planning to add solar, since many of the solar chargers provide four-stage chargers and remote temperature compensation.
